SPECIFICATION forming part of Letters Patent No. 631,563, dated August 22, 1899. Application filed January 10,1899. Serial no. 701,693. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH DUFFY, a citizen of the United States, residing in Paterson, in the county of Passaic and State of New J ersey, have invented certain new and useful Improvements in Orgauzine-Spinners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had'to the accompanying-drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to machines for spinning organzine-warp; and it has reference par,- ticularly to that class of machine of this nature referred to, for example, in Letters Patent Nos. 525,192 and 602,254, issued to me August 28, 1894, and April 12, 1898, respectively.

The principal objects of the invention are to improve upon the mounting arrangement of the spindles for the delivery-bobbins of a machine of the class referred to and upon the stopping mechanism for the spindles of both the receiving and delivery bobbins.

In view of the foregoing the invention consists in the improved spinning-machine and in the combination and arrangement of its various parts, substantially as will be here: inafter described, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, Figure l is a sectional view of the machine provided with my improvements. Fig. 2 is a front View of a portion of my improved ma chine, enough of the mechanism being shown to clearly illustrate my invention; and Fig. 3 is a top plan View of that portion of the machine which is shown in Fig. 2, one of the spindles and its whirls being removed.

In said drawings, a indicates the usual spindle-rail of a spinning-machine, upon which are supported, as hereinafter described, the various spindles for both the receiving and the delivery bobbins.

a indicates an auxiliary rail which is suspended beneath and parallel to the spindlerail a by means of brackets of.

b designates a series of cylindrical sockets which penetrate the spindle-rail a, each bein g sustain ed thereby through the medium of a rounded flange b at its upper end, said flange being slightly larger than the opening through which the socket projects. The diameter of the socket is slightly less than the opening through the spindle-rail, and the socket is therefore movable into various positions. The position of eachsocket is con trolled by means of a bolt b which projects through the auxiliary rail and through an elongated transverse aperture 19 formed in a flattened extension 12 at the lower end of said socket. The construction just described'not only renders each socket adjustable, but also makes it possible to. reverse the position of the same when the parts become worn unequally.

Each of the sockets receives and forms a bearing for the pintle c of the bolster b for the spindle of a delivery-bobbin, said bolster being carried by the pintle through the medium of a horizontal arm 0, integrally connecting these elements. The pintle has an enlargement 0 which rests upon the top of the flange b of the socket, and it is prevented from an undue upward movement out of the socket by means of a screw 0 projecting through the wall of said socket and engaging an annular groove 0 in said pintle.

The bolsters for the spindles of the deliverybobbins are arranged in pairs, and they project an appreciable distance beneath the spindle-rail, extending through elliptical or other elongated transversely-arranged openings b in said spindle-rail, so as to be free -to move for some distance about the pintles as axes. Theends of a curved metallic spring bear against the downwardly-projecting ends of each pair of bolsters, said spring being rendered adjustable by. means of a set-screw d, which works in a lug 01 extending downwardly from the spindle-rail, said set-screw bearing against the spring midway its ends. Said springis maintained against undue downward movement by flanges d upon the bolsters.

e e designate the spindles for the deliverythe receiving-bobbin, said bolster being sta- Y tionarily secured to the spindle-rail in any well-known manner. f designates the whirl for said spindle f, and g designates the continuous driving-belt which extends between the two series of whirls, being adapted to actuate said whirls so long as the spring (Z is free to act to force the bolsters Z1 rearwardly.

h designates a rail or support from which projects forwardly a series of thread-guides h, secured thereto in any desired manner and corresponding to the several delivery-bobbins.

tdesignates a rod connecting portions of the frame of the machine and over which the threads from the delivery-bobbins pass in their upward movement toward the arm j, which projects forwardly from a suitably-supported rail j and over which said threads also extend.

it designates a thread-guide situated below the armjand supported upon a suitable rail 7;.

Z Z are two rollers disposed the one above the other, the lower one being journaled in a fixed position and the upper one being loosely journaled in recesses l at the free end of a bifurcated lever m, fulcru med upon a bracket 'm, that is mounted upon a rail or beam m of the frame of the machine. Having passed the thread-guide 7a, the thread extends down back of the upper roller and then between the rollers, where the two threads from the deliverybobbins are doubled, they having been previously twisted. From the lower roller Z the thread extends downwardly to a spinning-rin g 71, of any well-known construction and carried upon a traverse-rail a, controlled by a vertically-reciproeating rod or traveler M, which is guided in a bracket n supported upon the spindle-rail a. The spinning-ringn incloses a receiving-bobbin a, which is carried upon the spindle f and upon which the thread or yarn is finally spun in the usual manner.

designates a hanging rod which is pivotally connected to the rear end of the lever m at its upper end and to which, near its lower end, is connected the braking devices for the several spindles.

The braking device consists of a curved or substantially horseshoe-shaped bar 1), from each of whose free ends extends laterally an arm 17 and from whose rear portion extends upwardly another arm p carrying a brakeshoe 11 preferably formed of rubber. The arms 1) are adapted to bear against the bolsters of the spindles for the delivery-bobbins, and the brake-shoe p of the armp is adapted to bear against the whirl of the receiving-bobbin, and for this reason the curved bar straddles the bolster of the receiving-bobbin. It is obvious that the brake-shoe p and the arms 1) may be adapted to bear against any other revolving portion of the driving means for the bobbins than those above particularly referred to, and consequently, moreover, the shape of the braking device proper may be somewhat altered, if desired. Said braking device is operated through the medium of a bell-crank lever g, which is fulcrumed in a bracket q, supported upon the spindle-rail (1 one arm of said bell-crank leverbein g pivotally connected to the braking device and the other arm thereof being likewise connected to the rod 0. In order to permit a true vertical movement of said rod 0, the arm of the bellcrank lever to which it is connected is provided with a slot receiving the pivoting element. The weight of the rod 0 overbalanees that of the roller Z, and hence has a tendency to lift said roller. The parts are normally sustained in the position in which they are shown in the drawings by an arm 1, provided with a roller 1', which bears against the under side of the rear portion of the lever 071, said arm being an upward extension of a weighted lever N, which is fulcrumed in a projection r of the bracket m and whose rear portion normallybears against the under side of said projection.

s designates a hanger pivotally secured to and depending from the rear end of the lever 1' and carrying a block .9, which is supported upon slides s of said hanger for horizontal movement.

25 designates one of a pair of fallers for the threads from the delivery-bobbins, and a des ignates a faller for the single thread which is produced after the doubling operation. Each of these fallers is provided at its outer end with a loop t and a, respectively, through which the thread passes. The rear end of the faller t is connected to one arm of a bellcrank lever 25 which is f ulcrumed in the bracket m and whose other arm is pivotally connected to the block The rear of the faller n is pivotally connected to a lever which is fulcrumed in a bracket a, extending from the rail m and is so curved and weighted at its free end as to tend to draw the faller rearwardly. The faller It is guided for horizontal movement by a bracket to, extending from the rail m 1 A connecting-rod a is pivotally secured to the lever 10 and the block 5, being adapted to transmit movement from the former to the latter.

t" designates a spur-wheel which is situated in con tiguity to the block 5', being constantly rotated while the machine is in operation.

It should be remarked that, if desired, a guide 10, supported upon the railm", may be provided for steadying the lower end of the hanger s.

y designates a rod which extends above and substantially parallel to the spindle-rail a, being supported thereon by suitable standards y. This rod is inclosed in a tube 3/, preferably formed of rubber and somewhat loosely secured thereon, so as to be turned into various positions. It will be noticed that the rod y is disposed directly oppositeto the whirls of the spindles of the delivery-bobbins and that it forms an abutment against which they may impinge. I

The operation of the machine may be thus described: The several whirls are normally maintained in operative contact with the driving-belt g by means of the spring (Lwhiel tends to force the whirls 6 6 carried upon the bolsters b rearwardly about the pintles c as axes. It will be seen that if the thread breaks at any point between the rollers H and the delivery-spindles the weight of the faller 25 will be free to actuate thebell-crank lever t and the block 8', which latter element will consequently be moved so as to be engaged by the spur-wheel v, the impact of which wheel forces the hanger downwardly, and consequently turns the lever r upon its fulcrum, so that the arm '2", which normally supports the lever m, will permit the latter, owing to the weight of the rod 9, to fall. If the thread breaks between the roller Z and the receiving-bobbin, the weighted lever a will act to move the block 8 into engagement with the revolving spur-wheel v, with the same ultimate dropping of the rod 0 as a result. This dropping of the rod 0 will throw forward the braking device proper, the brake-shoe p bearing against the whirl and stopping the rotation of the spindle f" and the arms p p, forcing the bolsters b forwardly against the action of the spring at and into such position that the whirls e 6 will bear against the rubber tube on the rod y and their rotation stopped. The separation of the two sets of whirls will of course effect a release of the belt 9, so that it will no longer act upon them.

It should be remarked that when the lever 'm is actuated the rollers Z Z are immediately separated and their action on the thread stopped.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
